Some wrong options are close on purpose. Liver in question 2 is the largest organ inside the body, but the skin is larger; Gallbladder in question 4 stores bile but does not make it; and Ligaments in question 9 join bone to bone, not muscle to bone. Quizoma's results show the accuracy of every question, so you will see straight away which idea the class has mixed up.

Students can use the same set to revise on their own: import it, switch on Show Score and Retake, and it becomes a practice test they can take until every answer sticks.

Timing and points are set on the quiz when you import, not in the file. If you would rather not import at all, you can type the questions into the online quiz maker directly.

What is in the file

One row per question: the question, then the options, then a final correct column holding the number of the right option. Where more than one option is right, the numbers are joined with a |. The first lines look like this:

question,option1,option2,option3,option4,correct
Which organs filter the blood to make urine?,Liver,Kidneys,Stomach,Lungs,2
How many bones are there in an adult human body?,106,206,306,186,2

Open it in any spreadsheet to edit, and save it as CSV again before importing — an .xlsx file is not read. The same format is described on the templates page.
